To all whom it my camera:

Be it known that 1, WILLIAM E. EVANS, a

ton, in the town of Johnston, in the county of Providence and State of Rhorle lsland, have invented certain-new and useful Improvements in Spools, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to spools, and has for its object to construct a spool in such I manner that its com onent parts may be separately packed for shipment, so as to occupy but little space, and subsequently asrequired length withbut sembled; that its component parts are interchangeable, and when manufactured in many different sizes, may be assembled so that a very large number of sizes of spools may be economically reduced; that no special tools are requir" in the construction of the parts or in the assembling thereof, such as are ordinarily r uired in the manufacture of spools; and t at in case of breakage of any of the component parts anew partmay be easily supplied, so that the spools may be easily repaired and kept in good condition at small expense.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed out in the ap ended claims.

11 the accompanying" drawings: Figure 1 is a side elevation and partial longitudinal vertical section of a spool embodying this elevation. Fig. 2 is a transverse section of the spool shown in Fig. 1, taken on thedotted line 2-2'. Fig; 3- is a detail of the head in perspective showing the centerhole and key. Fig. 4- is all end view of the barrel. Fig. 5 is an end view of the plug showing the key-ways formed therein. Fig. 6 is a central longitudinal section of one end of the spool taken between the key-ways.

Fig. 'T shows a portion of the plug sectioned on line 7-7 of Fig. 5 throughone of itlhe Cindentations or key-ways in its tapering The barrel a is usually made of wood. It is cylindrical in formand prefera'bfy tubular, and it has at each end an internally screw-threaded bore to receive an externally screw-threaded retaining-plug. Its ends are made fiat to provide seats 0 large area to engage the heads. It may be made of any necessitating the suitable material of a hard or tough nature.

It is circular in form and is made as a flat plate. It has a center hole I) through it, which is preferably made tapering from one face to the other. The smaller diameter of the center hole is substantially the same as the diameter of the internally screw-threadedbore in the end of the barrel. It is preferably recessed on its inner face to receive the end of the barrel.

The reinforcing plate 0 is adapted to enage the head when the parts are assembled.

"is plate is also composed of compressed fiber or other suitable material. It is cireular in form, has a center hole 0 through it which isal'so made tapering from one face to the other and the diameter of the centerhole is somewhat larger than the diameter of the center-hole in the head. It is preferably dished in such manner that when placed upon the head its outer edge and central part only will engage it, but it may be curved-or dished to otherwise engage or support the head in any suitable manner.

(i represents the retaining-plug which is preferably made of Wood. It has a cylinric'al externally screw-threaded body portion of a diameter to enter the internally screw-threaded bore in the barrel, and ithas a tapering head, which head is made long enough to extend through the center-holes of both the reii' forcing plate and the head,'and large enough in diameter to snugly fit said center-holes, and its taper corresponds to the taper of said center-ho es, so as to engage the walls thereof from one face to the other. When assembling the parts the screwthrea'ded' portion of the retaining-plug is projected through the center-holes of both the reinforcin plate and head and is screwed into the bore in the end of the barrel and is turned thereinuntil it tightly holds the parts assembled.

For the purpose of turning the screwthreaded retaining-plug without the necessityof providing spe'c1al tools, for accomphshing' this result the head of said plug may be formed with one or more key-ways d in the side of its tapering head, two being herein shown, and the head 6 may be provided with corresponding keys 6 at the edge of its center hole which enter said key-ways,

and thereby connects the plug and head in such manner as to prevent independent rotation of either with respect to the other,

fiber and the screw plug is formed of Wood,

or much softer material, it is found only necessary to form one or more keys or slightly projecting members 6 around the outer face of the central hole through said plate, and then as the plug is screwed into position in the barrel these projections or key members:

are forced to embed themselves into the softer tapering face of the plug head thereby forming natural keyways therein, and then said head I) may be grasped by the hand, to-

produce a greater leverage, to assist inturning the plug'tightly into position in the bar-' rel, locking the same therein by means of;

By this manner of forcing orressing the projections into the head tof friction.

form recesses therein asthe head and plug are screwed into positlon together, 1t is found that said heads may be assembled very much quicker, as it is not necessary to place the keys in any particular position to fit into previously prepared key-Ways, it being only necessary to place the members in position atthe end of the barrel when by setting up the plug in the manner above described the whole-is locked firmly together.

It is sometimes necessary and usually desirable to securethe parts when assembled in such manner as to prevent loosening by ordinary usage and in the form shown in Fig. 1, this result is accomplished by applying to the engaging surfaces a coating of glue or.

other adhesive material. As the heads are the particular parts which it is desired shall be held securely in place, they may be held from rotation by means of pins 6* which are driven through the reinforcing-plates and heads and into the ends of the barrel. Both the adhesive material and the pins may be employed if desired. I do not, however, desire to limit my invention to any particular means or provision for turning the retaining plug, or to any particular means or provision for securing the parts in assemled position.

. The spool thus constructed possesses many important advantage, as for instance, it may be shipped knocked-down that is to say, its component parts may be packed for shipment and nested so as to occupy but little space, being subsequently assembled by the receiver without the aid of any special tools. Different. sizes of heads and reinforcing plates may be made and-also different sizes and lengths of barrels, and the several comthat a purchaser may select the particular sizes of any of the component parts to make up a spool suitable to meet his particular requirements. As the invention is suscep tible of a wide variation in sizes of the component parts a lzfi ge variety of sizes of spools may be economically produced. In

case of breakage of any particular part of I the spool a new part may be easily supplied.

Having described my invention, What I claim as new and desire to secure by Letters Patent is: i

l. A spool consisting .of a cylindrical barrel having an internally screw-threaded bore at each end, a head at each end of said barrel formed of comparatively thin, material each provided with a central bore, a reinforcing plate having a central bore for supporting each head, and screw threaded retaining plugs adapted to enter the threaded barrel bores, .eachof said plugs being provided with a tapering head which is adapted to engage the center hole of said plate and head for the purpose of firmly securing them to the barrel.

' 2. A spool consisting of a cylindrical barrel having an internally screw-threaded bore at each end, a head at each end of said barrel formed of comparatively thin material each provided with a central bore, a reinforcing plate having a central bore for supporting each' head, and screw threaded retaining plugs adapted to enter the threaded barrel bores, each of said plugs being provided with a tapering head which is adapted to engage the center hole of said plate and head for the purpose of firmly securing them to the barrel, and locking means in the spool head for engaging the plug whereby said plug maybe turned into the barrel bore by said head. v

3. A spool consisting of a cylindrical barrel having an internally screw-threaded bore at each end, spool heads each having a tapering center hole through it formed with a key, retaining plugs each comprising an externally screw-threaded cylindrical portion adapted to enter the bore in each end of the barrel and a tapering head on each plug adapted to extend through the center hole in each of said spool heads, said plugs being provided with key-ways to receive the keys in said spool heads, substantially as described.

4. A spool consisting of a cylindrical barrel having an internallyscrew-threaded bore at each end, a headat each end ofsaid barrel formed of comparatively thin material each provided with a tapering central bore, a key or projection formed in said bore. a reinforcing *plate having a enter the threaded barrel bores, each of said plugs being providedwith a tapering head which is adapted to en age the center hole of said plate and head or the purpose of firmly. securing them to the barrel, said plug being provided with keyweys to receive the keys in said spool head whereby said plug maybe turned into the barrel bore by said head.
